Mother Bunker, who had been much worried, "that
home will be the very best place in the world after this. I will not let
Mun Bun out of my reach again. How does he manage to get into so much
trouble?"

"Why, Muvver!" sobbed the littlest Bunker, "I just tumble in. I tumbled
into this box and then they locked me in."

"How does he tumble into trouble?" demanded Vi, staring at Mun Bun.

"I _know_ there is a riddle about it," said Laddie thoughtfully. "Only I
can't just make it out yet."

They were all very glad that Mun Bun was not hurt. But it did seem that
he would have to be watched very closely or he might disappear again.

"He's just like a drop of quicksilver," said Cowboy Jack. "When you try
to put your finger on him, he isn't there."

Just then the great horn blew to call everybody to the fort, for Mr.
Habback was ready for the big scene of the picture. The little
Bunkers--at least, all but Mun Bun--were eager to respond, for they
wanted to be in the picture. Mother, however, kept the little boy with
her, and they only watched the picture when it was made. That satisfied
Mun Bun just as well, for he did not believe that he looked nice enough
to go to a photographer just then.

"I guess I'll have my picture taken when I get back to Pineville,
Muvver," he said. "I'll like it better."

But the rest of the party would never forget that exciting day. The
Indians led by Black Bear attacked the fort, and there was much shooting
and shouting and riding back and forth. The shooting was with blank
cartridges, of course, so that nobody was hurt.

But even the ponies seemed to be excited, and Russ told Rose he was
quite sure Pinky and his pinto, who were both in the picture, enjoyed
the play just as much as anybody!

"Only, they will never see the picture when it is on the screen. And
daddy says we will, if nothing happens. When the picture comes to
Pineville we can take all the children we know at school and show 'em
how we worked for the picture company and helped make 'A Romance of the
Santa Fe Trail!'"

This, later, they did. But, of course, you will have to read about that
in another story about the Six Little Bunkers.

Mr. Habback thanked the Bunkers when the work was done, and in the
middle of the afternoon Cowboy Jack took them all back to the ranch
house again in his big blue car, one of his cowboys leading in Pinky and
the pinto pony later.

On the way to the ranch Russ and Rose heard daddy tell moth
